Abstract
La présente invention concerne un procédé de handover entre deux cellules d'un réseau cellulaire de radiocommunication mobiles, chaque cellule étant munie d'une station de base (BTS1, BTS2), procédé selon lequel une station mobile (MS)communicant avec une première station de base (BTS1), dite ancienne station de base: reçoit un ordre de changement de station de base (HANDOVER CMD); transmet un message contenant une information d'établissement de connexion (SABM) ou des données utiles à la deuxième desdites stations de base, dite station de base (BTS2), dite nouvelle station de base, en tenant compte d'une avance temporelle avec laquelle ladite station mobile doit retarder l'émission de ses messages à destination de la nouvelle station de base (BTS2). L'ordre de changement de station de base (HANDOVER CMD) indique en outre au mobile (MS) de ne pas émettre de message d'accès en direction de la nouvelle station de base (BTS2), et l'avance temporelle est déterminée par le mobile (MS) lorsqu'elle ne lui est pas communiquée dans l'ordre de changement de station de base (HANDOVER CMD).
